Abstract

Binding of a series of mammalian glycoconjugates to three soluble rat lung lectins was determined with a quantitative assay. The three lectins, RL-14.5, RL-18, and RL-29, had a similar apparent affinity for lactose and associated with the same critical determinants, which included positions 4 and 6 of Gal and part of Glc. Derivatization at position 3 of Glc in lactose markedly reduced reactivity with the three lectins. For RL-14.5 and RL-29 the determinant extended specifically to the 3-hydroxyl of Glc which must be equatorial. In contrast, the stereochemical requirements for RL-18 were less specific, and Gal beta 1-3GalNAc bound as well as lactose. For RL-29 activity was markedly enhanced by GalNAc alpha 1-3 substitution on Gal, a modification which had little effect with RL-18 and inhibited binding to RL-14.5. Combinations of these residues in larger oligosaccharides and glycopeptides did not substantially enhance binding above that which might be expected from the sum of the constituent beta-galactoside residues. Although these lectins showed overlapping specificities, their binding properties are sufficiently different to suggest selective interactions with naturally occurring mammalian glycoconjugates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
